Title: Kenji Tokui: Innovator in Optical Recording Technology
Introduction
Kenji Tokui is a prominent inventor based in Hitachinaka, Japan. He has made significant contributions to the field of optical recording technology, holding a total of 6 patents. His innovative work has advanced the capabilities of optical storage mediums, making them more efficient and effective.
Latest Patents
Tokui's latest patents include an optical recording method, an optical recording apparatus, and an optical storage medium. In his first patent, data is recorded in a phase-change optical storage medium that features data layers. A first recording pulse sequence is generated for recording to a first data layer located most remote from a beam-incident surface. This sequence includes a recording pulse that carries an erasing power and a recording power that rises from the erasing power, along with a cooling pulse that carries a bottom power lower than the erasing power. Additionally, a second recording pulse sequence is generated for recording to a second data layer, which also includes a recording pulse, a cooling pulse, and an erasing top pulse.
Another notable patent involves a phase-change optical recording medium that has a tracking signal smaller than the saturation value. This medium consists of a substrate and a recording layer with multiple tracks for storing information. The material of the recording layer is initialized in a crystalline state, ensuring that the amplitude of the tracking-detection signal remains smaller than the saturation value. This signal is obtained by receiving a reflected beam from the recording layer when it is irradiated with a laser beam in an off-track state while the optical storage medium is being rotated.
